Abstract (de)

Bei einer chloridsensitiven Elektrodenmembran, welche eine Polymermatrix mit zumindest einer elektroaktiven Komponente aufweist, wobei die Polymermatrix ein Epoxidharz mit einer Aminverbindung als Härter enthält, wird zur Verminderung der Verschmutzungsneigung und Erhöhung der Standzeit vorgeschlagen dass das Epoxidharz zumindest einen epoxidharzkompatiblen Flexibilisator aufweist, sowie dass der Anteil an Epoxidharz samt Flexibilisator an der Elektrodenmembran bei über 60 Gew.% und jener der elektroaktiven Komponente bei maximal 35 Gew.%, vorzugsweise bei maximal 30 Gew.%, liegt. <IMAGE>
